Rice from Site 4 (Kham Muang) showed the highest antioxidant activities, with elevated values in DPPH radical scavenging (923.17 µg Trolox/g), FRAP (1001.39 µg FeSO₄/g), total phenolic content (816.26 µg GAE/g), and total anthocyanin content (51.86 g c3g/100g), indicating favorable conditions for phenolic compound biosynthesis. Conversely, rice from Site 3 (Khong Chai) had the highest amylose content (14.20%), resulting in lower peak viscosity and greater setback viscosity, which suggests increased starch retrogradation and firmer rice texture. Site 1 (Mueang) rice displayed the highest onset and peak gelatinization temperatures, indicating a more stable starch structure, while Site 4 had the highest peak viscosity (189.58 RVU) and breakdown, reflecting a starch with greater water absorption and gel-forming capacity. These variations are linked to differentiate &nbsp;in soil texture, drainage, and environmental factors, which affected the rice’s nutrient uptake, antioxidant activity, and starch properties.</p> 2025-09-24T00:00:00+07:00 Copyright (c) 2025 https://li04.tci-thaijo.org/index.php/IJAT/article/view/7533 Production of chlorophyll-rich powder from Moringa oleifera leaves using dehumidification and intermittent drying: impact on drying characteristics and chlorophyll retention. 2025-09-24T15:34:39+07:00 Djaeni, M. moh.djaeni@live.undip.ac.id Hadiyanto, H. moh.djaeni@live.undip.ac.id Suherman, S. moh.djaeni@live.undip.ac.id Handayani, N. A. moh.djaeni@live.undip.ac.id Utari, F. D. moh.djaeni@live.undip.ac.id <p>Results demonstrated that zeolite enhanced moisture removal efficiency, with significant reductions in moisture ratios which observed at higher temperatures. Specifically, at 40°C, the moisture ratio improved from 0.9175 to 0.8924, while at 80°C, it decreased from 0.8039 to 0.6275.

P. mpmontecalvo@up.edu.ph <p>Water spinach (<em>Ipomoea aquatica</em> Forsk.) is important for its nutritional, economic, and environmental benefits. However, pathogen infections can impact its production. This study aimed to identify the fungal pathogen responsible for leaf spots on lowland water spinach. Infected leaves showed brown necrotic spots surrounded by yellow halos. Pathogenicity assays confirmed the virulence of the fungal pathogen WS1 in both lowland and upland water spinach. Through morphological, cultural, and molecular characterization, the pathogen was identified as <em>Diaporthe batatas</em> Harter &amp; E.C. Field. Key characteristics of the fungal isolate included hyaline, septated, and branched hyphae, with conidia measuring 4.1 to 8.3 µm in length and 1.8 to 3.2 µm in width. The isolate displayed distinct growth patterns on various artificial media with transparent, flat, rhizoid mycelium on water agar; white, velvety mycelium with black pycnidia on malt extract agar and potato dextrose agar; and dark brown to black filamentous colonies on Sabouraud dextrose agar. Sequencing of the internal transcribed spacer (ITS) and β-tubulin genes matched reference sequences of <em>D. batatas</em>.

Fourier Transform Infrared Spectroscopy and Field Emission Scanning Electron Microscopy were employed for film analysis. FTIR spectra indicated the presence of characteristic functional groups including O–H, C–H, C=C, C–O, C–OH, sulphate esters, C=O stretching, and CO–O–SO₃ stretching vibrations. FESEM imaging demonstrated a homogeneous surface with a dense and compact structure. The films' functional efficacy was assessed using chicken meat as a model system. The addition of curcumin and limonene facilitated observable color alterations corresponding to meat freshness, confirming the film's utility as a freshness indicator. In addition to indicating spoilage, these natural additives conferred antioxidant and antibacterial properties. The study underscored the potential of biodegradable κ-carrageenan films fortified with natural bioactive compounds as sustainable packaging solutions.

Oxalate is among the most common anti-nutrients found in many agricultural products. This study investigated the effects of soaking in sodium chloride (NaCl) solution and boiling treatment on the physicochemical properties, nutrients and oxalate content in taro tuber samples grown in North Sumatera, Indonesia. The data showed that the physicochemical properties (colour and pH) of the samples were not significantly impacted by both treatments. From the aspect of proximate compositions, soaked samples did not vary significantly from the control. On the other hand, noticeable drop in the ash, protein, fat and fibre contents were observed in the boiled samples. Both soaked and boiled samples recorded higher carbohydrate contents than the corresponding control. The treatments led to a loss of 29.69% to 99.23% of total oxalates in the samples, with boiling treatment exhibiting the greatest effect. Moreover, both treatments showed positive correlation with the concentration of salt and treatment duration, where a higher concentration of NaCl and a longer duration resulted in a higher loss of oxalate. However, only T4 could be regarded as low-oxalate content Thus, further treatments need to be considered to lower the amount to a greater extent.</p> 2025-09-24T00:00:00+07:00 Copyright (c) 2025 https://li04.tci-thaijo.org/index.php/IJAT/article/view/7578 Exploring the therapeutic efficacy of ethanol extracts from Melia azedarach Linn. fruit-seeds against oxidative stress induced by melon flies on bitter melon. 2025-09-24T15:34:15+07:00 Nhung, T.

Enzymatic assays demonstrated that FSMA treatments, particularly at 125 and 652 ppm, significantly enhanced the activities of key antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD). A strong inverse correlation was observed between the levels of oxidative stress biomarkers and the activities of these antioxidative enzymes, suggesting a mechanistic role of FSMA in modulating redox homeostasis. The findings underscore the efficacy of FSMA in mitigating oxidative damage through the activation of endogenous antioxidant defense systems.

Notable changes in body weight, relative kidney weight, and kidney structure were observed, with the normal group exhibiting the highest body weight (40.34 ± 0.42 g) (p &lt; 0.05) and the lowest relative kidney weight (28.61 ± 0.23%) (p &lt; 0.05). In contrast, the PARA group showed reduced body weight (27.66 ± 0.46 g) (p &lt; 0.05) and increased relative kidney weight (68.99 ± 0.82%) (p &lt; 0.05). Treatment with NAC and ESBA improved these parameters, with the PARA+NAC and PARA+ESBA400 groups approaching normal values. Furthermore, malondialdehyde (MDA) and hydrogen peroxide (H₂O₂) levels were significantly elevated in the PARA group (p &lt; 0.05), indicating oxidative stress, while NAC and ESBA supplementation effectively reduced these levels across all tissues (p&lt;0.05). Analysis of glutathione (GSH) and total antioxidant capacity (TAC) revealed higher levels in the normal group compared to the PARA group (p &lt; 0.05), with NAC and ESBA restoring GSH and TAC levels (p &lt; 0.05). Antioxidant enzyme activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were also significantly improved with treatment (p &lt; 0.05). Additionally, immunomodulatory effects were observed, as evidenced by changes in white blood cell count, nitroblue tetrazolium positivity, and total immunoglobulin levels (p &lt; 0.05). ESBA treatment notably restored immune function by decreasing inflammation markers and enhancing phagocytic activity (p &lt; 0.05).

G. agquitalig23@gmail.com Parayao, A. M. agquitalig23@gmail.com Waing, K. G. D. agquitalig23@gmail.com <p>Fungal endophytes are considered as natural bioactive reservoir that could be used as agents for antifungal activity. <em>Echinochloa colonum</em> (L.) Link an invasive rice weed compete with plant resources but houses several essential endophytes. However, a notable gap exists since few to none were conducted regarding the use of fungal extracts isolated from the weed <em>E. colonum</em>. Thus, evaluation of fungal endophytes from weeds needs to be established that may lead to development of biocontrol agent against fungal pathogens. Therefore, extracts from endophytic fungi isolated from the leaves of <em>E. colonum</em> were evaluated its antifungal activity against rice plant pathogens such as <em>Aspergillus flavus, Fusarium oxysporum</em>, <em>Rhizoctonia solani</em>, and <em>Aspergillus oryzae</em>, <em>Curvularia umbiliciformis</em>, <em>Curvularia chiangmaiensis</em>, and <em>Bipolaris panici-miliacei </em>were successfully isolated from the leaves of <em>E. colonum</em> and were &nbsp;identified based on cultural, morphological and molecular data. Additionally, using morphological and cultural techniques, <em>Aspergillus</em> sp. was also identified as another endophyte. Identified fungi were fermented using solid state fermentation to obtain fungal extracts. The 50µL of endophytic fungal extracts were used and exhibited varying antifungal activities in the agar well diffusion method. Extracts from <em>Aspergillus</em> sp., and <em>B. panici-miliacei </em>showed absence to weak antifungal activity against different fungal rice pathogens. While, <em>C. chiangmaiensis </em>extracts showed weak (11.83 ± 0.06 mm) to comparable (30.83 ± 0.40 mm) antifungal activity against <em>A. flavus</em> and<em> F. oxysporum </em>after 48 hours of incubation. Among the four fungal extracts, <em>C. umbiliciformis</em> extracts showed antifungal activity against <em>A. flavus</em> (18.53±0.40 mm), <em>F. oxysporum</em> (11.23±0.15 mm), and <em>R. solani</em> (31.73 ± 1.00 mm), and <em>A. oryzae</em> (36.77 ± 4.89 mm) after 48 hours of observation. Furthermore, statistics revealed that <em>C. umbiliciformis</em> extract showed comparable antifungal activity against <em>R</em><em>. solani</em>. Therefore, fungal endophytic extracts can be expressed as a good source of antifungal agent against selected rice pathogen.</p> 2025-09-24T00:00:00+07:00 Copyright (c) 2025 https://li04.tci-thaijo.org/index.php/IJAT/article/view/7592 Antimicrobial and plant growth-promoting activity of Bacillus subtilis isolated from mangrove soil. 2025-09-24T15:34:01+07:00 Shinde, P.

J. pampi.chakraborty@xaviers.edu Chavan, S. pampi.chakraborty@xaviers.edu Chakraborty, P. pampi.chakraborty@xaviers.edu <p><em>Bacillus subtilis</em> strain was isolated from mangrove soil and evaluated for its biocontrol and plant growth-promoting potential. The strain exhibited key traits including indole-3-acetic acid (IAA) production, biofilm formation, and tolerance to high salinity (up to 10% NaCl). It showed broad-spectrum antimicrobial activity, inhibiting the growth of both fungal and bacterial pathogens. Antifungal activity was demonstrated using well-diffusion and dual-overlay assays, effectively suppressing <em>Aspergillus niger</em>, <em>Rhizopus arrhizus</em>, and <em>Mucor mucedo</em>. Antibacterial effects were observed against <em>Escherichia coli</em>, <em>Bacillus albus</em>, and <em>Xanthomonas</em> sp. The cell-free supernatant of the isolate significantly inhibited fungal spore germination, as confirmed by turbidity assays. LC-MS analysis of the supernatant revealed the presence of antimicrobial compounds, including palmitic acid derivatives, fatty acid amides, and pyridine-based molecules. Bio-priming wheat seeds with this <em>Bacillus</em> sp. led to enhanced seed germination and increased shoot and root lengths, especially under saline soil conditions. These findings highlight the potential of this mangrove-derived <em>B. subtilis</em> strain as a promising bioinoculant for sustainable agriculture, particularly in salt-affected environments.</p> 2025-09-24T00:00:00+07:00 Copyright (c) 2025 https://li04.tci-thaijo.org/index.php/IJAT/article/view/7593 Effect of composted plant based and animal derived materials on Chinese kale (Brassica oleracea var. alboglabra) performance in raised beds. 2025-09-24T15:33:58+07:00 Somniyam, P. Vimolchat.som@uru.ac.th Pupakdeepan, W. Vimolchat.som@uru.ac.th Phatdiphanpreeda, P. Vimolchat.som@uru.ac.th Somniyam, V. Vimolchat.som@uru.ac.th <p>The application of organic planting materials influenced the physicochemical properties of growing media and significantly affected the growth and yield of Chinese kale cultivated in raised beds. Composted animal manures, particularly porcine and poultry manure, provided higher nitrogen and phosphorus levels, enhancing vegetative growth. Among the plant-based materials, rain tree leaves contained the highest nitrogen content; however, high nitrogen alone did not guarantee optimal growth, emphasizing the importance of nutrient balance and physical media structure. Rice husk biochar improved porosity, bulk density, and water-holding capacity, yet failed to achieve the highest yield when applied alone. The combination of filter cake or old mushroom lumps with porcine manure led to superior plant height, stem diameter, canopy width, leaf number, and leaf size. These treatments also showed higher leaf greenness, highest fresh and dry biomass, and lower root-to-shoot ratios, reflecting efficient biomass allocation toward harvestable parts. Although plant-based and animal-based materials showed significant individual effects, their interaction was not statistically significant, suggesting additive rather than synergistic effects. The superior performance of magnesium-rich materials such as filter cake highlighted the role of magnesium in chlorophyll synthesis and leaf development. Overall, integrating nutrient-dense animal manures with structurally beneficial plant-based materials improved the fertility and physical quality of growing media, resulting in enhanced growth and yield of Chinese kale. These findings demonstrated the potential of locally available organic resources, particularly combinations of porcine manure with filter cake or mushroom waste, as viable alternatives to chemical fertilizers for sustainable leafy vegetable production in raised bed systems.</p> 2025-09-24T00:00:00+07:00 Copyright (c) 2025 https://li04.tci-thaijo.org/index.php/IJAT/article/view/7594 Effects of vermicompost on growth and yield of Japonica rice (Koshihikari Var.) in Thailand. 2025-09-24T15:33:57+07:00 Somniyam, V. somniyamp51@gmail.com Rangseesakorn, K. somniyamp51@gmail.com Krongtadech, D. somniyamp51@gmail.com Somniyam, P. somniyamp51@gmail.com <p>Significant differences were observed in plant height, number of tillers, and chlorophyll content. The 10% vermicompost treatment resulted in the tallest plants at 88 days. The combined vermicompost and chemical fertilizer treatment (T8) produced the highest number of tillers, though it did not differ significantly from the 20% vermicompost treatment (T4). Over time, vermicompost-amended treatments outperformed chemical fertilizer alone in most growth and yield parameters. Treatment 5 yielded the highest total seed count, while T4 resulted in the healthiest seeds and the greatest total fresh and dry seed weights. T4 also had the widest, longest, and thickest seeds, with a fivefold increase in total dry seed weight compared to the control. These findings strongly supported the application of vermicompost particularly at 10–30% for improved Japonica rice growth and yield, highlighting its potential for organic production systems.</p> 2025-09-24T00:00:00+07:00 Copyright (c) 2025 https://li04.tci-thaijo.org/index.php/IJAT/article/view/7595 Potency of some plant extracts as insect attractant in paddy field. 2025-09-24T15:33:55+07:00 Tanruean, K. fagrpspo@ku.ac.th Thongchai, W. fagrpspo@ku.ac.th Chammui, Y. fagrpspo@ku.ac.th Likittrakulwong, W. fagrpspo@ku.ac.th Upachak, P. fagrpspo@ku.ac.th Chamsuk, P. fagrpspo@ku.ac.th Poolprasert, P. fagrpspo@ku.ac.th <p>The brown planthopper, <em>Nilaparvata lugens</em> (family Delphacidae), rice green leafhopper, <em>Nephotettix virescens,</em> and zigzag leafhopper, <em>Recilia dorsalis </em>(family Cicadellidae) were determined to be the highest percentage frequency of occurrence in each bottle trap containing each lure.
